Niiden absorboivat kappaleet valmistetaan nontu siten että sellaista sellumassaa, joka on esimerkiJ la, paalin tai arkin muodossa, kuidutetaan kuivane 15 tehdään revinnäismassaa massamaton muodostamiseksi, massaan on massamatossa joskus sekoitettu ns. supea boivaa materiaalia mainittujen absorbenttien Ollesi rejä, jotka pystyvät absorboimaan monta kertaa omar verran vettä tai kehon nestettä.The present invention relates to a process for making a c structure which is contained in an absorbent article such as a sanitary napkin, a panty liner, a urinary incontinence cap, a diaper, a wound or wound dressing in a ciabsorbent and the like. , many different types. Their absorptive bodies are made by ducking so that the pulp, which is in the form of a bale or sheet, for example, is pulp dried to form a tear pulp to form a pulp mat, sometimes mixed with so-called pulp. a narrow bumping material of said absorbents being able to absorb many times Omar in water or body fluid.

Toinen ongelma piilee niin sanotussa uudelleenkost se on, siinä että jo absorboitunut kehon nesteen s kaisin kosketuksiin käyttäjän ihon kanssa, mikä ta ulkoisten voimien vaikutuksesta, esimerkiksi kun k 15 istuutuu. Yleensä halutaan, että artikkelin sellai joka käytössä sijaitsee lähellä vartaloa, pysyy ni kuin mahdollista.Another problem lies in the so-called rehydration that is already absorbed by the contact of the body fluid with the skin of the wearer, which is exerted by external forces, for example, when k is sitting. Generally, it is desired that an article such as this one, which is in use, be close to the body, as much as possible.
Hygieniatuotteiden pääosaa koskeva toinen toivomus 20 artikkelin tulee olla ohut, jotta sitä voidaan käy i *· hienovaraisesti kuin mahdollista.Another wish for the main body of hygiene products 20 articles should be thin so that it can be handled as subtly as possible.

Esillä olevan keksinnön päämäärä on saada aikaan edellä kaltainen absorboiva rakenne, jolla on erittäin hyvät a ominaisuudet ja joka pystyy ottamaan nopeasti vastaan n 5 myös levittämään sen koko materiaaliin. Materaalilla tu luummin olla vähäiset taipumukset kostua uudelleen, ja muodostaa erittäin ohueksi. Halutaan myös antaa käyttöö taistettu menetelmä sellaisten absorboivien artikkeleid tamiseksi, jotka määritellään johdannossa. Nämä päämäär 10 tut ominaisuudet saavutetaan valmistusmenetelmällä, jos nen partikkelimateriaali, joka sisältää 30-100, mieluum 50 ja mieluiten ainakin 70 prosenttia hiutalekuivattua muodostetaan kuivana rainaksi, jonka neliöpaino on 30 -ja joka puristetaan tiheyteen, joka on 0,2-1,0 g/cm3, ji 15 menetelmässä raina, jota tämän jälkeen ei kuiduteta eik sisällytetään absorboivaan artikkeliin sen absorboivana kenteena.The object of the present invention is to provide an absorbent structure of the above type, which has very good properties and is capable of rapidly absorbing n 5 and also spreading it throughout the material. The material is more likely to have a slight tendency to re-moisten and form very thin. It is also desirable to provide a workable method for the articulation of absorbent articles as defined in the introduction. These target properties are achieved by the manufacturing process if the particulate material containing 30-100, preferably 50, and preferably at least 70% of the flake-dried material is formed into a dry web having a basis weight of 30 and compressed to a density of 0.2-1.0 g. / cm 3, in the process of 15, which is not subsequently defibrated and included in the absorbent article as its absorbent field.

Materiaalilla on edulli hainen uudelleenkostuminen ja se tulee voida valmi täin ohuena ja pehmeänä. Valmistusprosessia toivot 15 yksinkertaistettavan. Sellainen valmis absorboiva rullamuodossa, jota voidaan käyttää tarvitsematta vähentäisi osittain aiemmin mainitun kuidutuslaitt paineilmakuljetinjärjestelmien ja mattoa muodostav teiston tarvetta, ja niin muodoin sellaiselle mate 20 on kysyntää.It is an object of the present invention to provide an article such as a sanitary napkin, a tampon, a pant protector, a baby diaper for urinary incontinence, a bed cover, a ciabsorbent for injury or wound, and the like, an absorbent having a high absorption capacity and a n throughout the material. The material has a favorable odor re-wetting and should be capable of being thin and soft. You hope to simplify the manufacturing process. A ready-to-absorb absorber in roll form that can be used without the need would partially reduce the need for the above-mentioned defibration device for pneumatic conveyor systems and mat forming equipment, and thus the demand for such mate 20 is.

Tiettyjen absorboi tikkeleiden tapauksessa on havaittu sopivaksi pehm riaalia vähän ennen sen käyttöä. Erästä materiaali mismenetelmää kuvataan myöhemmin.5 Untreated, dry form rolls have extremely good liquid absorption, dispersion properties, and have been found to be able to be used immediately as an absorbent for hygiene articles without pulping. In the case of certain absorbent articles, softness has been found shortly before its use. One method of materialization will be described later.
15 Kuivamuodostetulla rullamassalla on hyvä maton koo pysyvyys, mikä tarkoittaa sitä, että kun superabso materiaaleja käytetään kuivamuodostetussa rullamas rakeet sidotaan hyvin absorboivan aineen rakentees ne leviä, kun aine edelleen muutetaan absorboiviks 20 tuotteiksi.The dry-formed roll mass has a good mat size stability, which means that when superabso materials are used in the dry-formed roll, the granules are bonded to the structure of the highly absorbent material as the material is further converted into absorbent articles.

Sellaisella kuivamuodostetulla rullamassalla, joka 5 tavalla on pehmennetty, on erittäin hyvät tuoteomi sekä aiemmin mainitut hyvät absorptio-ominaisuudet pehmennysprosessi ei vaikuta suuressa määrin.The dry-formed roll mass which is softened in 5 ways has very good product properties and the good absorption properties mentioned above are not greatly affected by the softening process.

The non-softened ma normally has a uniform high density over the material k (61). The softening process to produce the material lamination has been disassembled to form a large number of separated (63) thin layers of fiber (62). 15 softening and de-lamination reduces the overall density whereby the original density of each individual ke is substantially maintained. Because the single layers retain a very high density, the good fluid-release properties are maintained without increasing the mass in the softening process. in the process, the total mass is always increased by 300 prose to 1-100% normally, depending on how much material is softened.

The results also showed that blood absorbed products having a highly absorbent material had lower values for wettability than material having a highly absorbent material. Such a material lacks a highly absorbent material, also spreads more efficiently. The results can also be seen patterned. Comparison products comprised of two different products are common in the market. The results were determined according to 5. According to the test results, at least one layer of the mass mat lacked absorbent material. Of course, this does not prevent this kind of material in the absorbent article.
